The How to: Find Existing Files and Directories in Isolated Storage example demonstrates the use of the GetFileNames method.

The following code example demonstrates the GetFileNames method. For the complete context of this example, see the IsolatedStorageFile overview.

    String[] dirNames = isoFile.GetDirectoryNames("*");
    String[] fileNames = isoFile.GetFileNames("Archive\\*");

    // Delete all the files currently in the Archive directory. 

    if (fileNames.Length > 0)
    {
        for (int i = 0; i < fileNames.Length; ++i)
        {
            // Delete the files.
            isoFile.DeleteFile("Archive\\" + fileNames[i]);
        }
        // Confirm that no files remain.
        fileNames = isoFile.GetFileNames("Archive\\*");
    }


    if (dirNames.Length > 0)
    {
        for (int i = 0; i < dirNames.Length; ++i)
        {
            // Delete the Archive directory.
        }
    }
    dirNames = isoFile.GetDirectoryNames("*");
    isoFile.Remove();
